At the time of her grandson's birth, a grandmother deposits $12,000.00 in an account that pays 2% compound monthly. What will be that value of the account at the child's twenty-first birthday, assuming that no other deposits or withdrawls are made during the period.
---
A(t) = P(1+(r/n))^(nt)
---
A(21) = 12000(1+(0.02/12))^(12*21)
---
A(21) = 12000(1.5214)
---
A(21) = #18,257.15
The complement of the given set is:
A* = {-1, 0, 1, 4, 5}

How to find the complement of the set?</h3>
For any set A on a universal set U, such that:
A ⊂ U.
The complement of A is the set of all the terms on U that do not belong to A.
Here we have:
U = {-3, -2, -1, 0, 1, 2, 3, 4, 5, 6, 7}
And the given set is:
A = {-3, -2, 2, 3, 6, 7}
Then the complement of A is:
A* = {-1, 0, 1, 4, 5}
(all the elements of U that are not in A).

Answer:
A = 9, B = 5, C = 3
the parabola opens upwards
y-intercept = 3
Step-by-step explanation:
Since the equation is f(x)=9x^2+5x+3, you can determine what a, b, and c are by associating it with a quadratics standard form, <u>ax^2+bx+c</u>. The numbers correspond with each letter in the skeletal equation.
To determine whether the parabola opens up or down, you can simply look at the a value. If <u>x > 0</u>, the the parabola will <u>open upwards</u>, whereas if <u>x < 0</u>, the parabola will <u>open downwards</u>.
To determine <u>y-intercept</u>, just plug in the value of 0 into x and solve for y.
Hey there!
In order to solve this problem, we can use the slope given two points formula:
y2-y1/x2-x1
Now, we can plug in our points to get:
1-0/5-0 = 1/5
Your answer is 1/5, or B.
Hope this helps!
